Why Do I Have A Shaky And Weak Feeling During First Day Of Period ?
Thanks for writing to us.
Cold sweats may be due to stress, syncope etc.
Sudden sweating and shaky feeling while you are having periods is most commonly due to a sudden heavy bleeding. You need to monitor yourself for the amount of bleeding you are having and if you are changing pads more frequently then the cause needs to be investigated under the guidance of your Gynaecologist.
The other causes that need to be ruled out are hypoglycaemia, sudden fluctuation in blood pressure, heart rate rhythm disorders, etc.
You also need to have your hemoglobin checked to rule out anemia.
Please visit your gynecologist to undergo physical check up and also to undergo relevant investigations required in your case.
I hope my answer and recommendations are adequate and helpful.
Waiting for your further follow up queries if any.
Regards.
